Bug Description

Binary package hint: gthumb

The Feisty version of gthumb seems to support raw files, but when I open a directory that contains a mix of .JPG and .NEF (Nikon RAW) files (my camera is set to record both raw and JPG versions of each picture), gthumb becomes unusably slow.

I can disable the display of NEF files using a filter, but this has two problems:

A) If NEF files are present the filter UI is unresponsive
B) the space used by the filter UI prevents met from sizing the thumbnail view as I'd like it.

It may be a bug, but when I turn off display of the file filter it also stops working.

I'm running Feisty i386 on an old but not unreasonably slow PC (1GB memory, AMD AthlonXP @ 1.8GHz).

gthumb can use libopenraw or dcraw to thumbnail NEF images.

dcraw is horribly, horribly slow (but stable). I assume you have dcraw installed.

libopenraw is new and possibly unstable, but it is very fast. You might try installing libopenraw and see if it makes life better for you. http://libopenraw.freedesktop.org/wiki.

The thumbnails do get cached, so gThumb should only be slow the first time that you load the folder. Does that happen for you?

gthumb is not build with libopenraw support. See bug 105546

The problem I have is not that the thumbnail generation is slow, but that gthumb is unresponsive while this happens. A typical directory I work with in gthumb will have 100s of pictures/RAW files. Generating thumbnails for all takes 10's of minutes, during which time i can't really use gthumb.

Yes, that's true. I've reported that upstream as http://bugzilla.gnome.org/show_bug.cgi?id=430618.

It's been a long time since this bug report got any attention (both here, and the upstream one too) and Feisty is not even supported anymore.

Is this still an issue? Thank you
